so i just bought that gameboy crystalis game from ebay to play in my GBA. i hope it's cool. is it a different story, or just a remake of the NES game?

and speaking of the NES version of crystalis, was anybody else disappointed at how easy the final battle was? i had borrowed the game from my girlfriend when i was in high school cause she always talked about it and said it was her favorite game. i played it for a long time and when i finally made it to the end i beat it in less than 2 mins...it was still a fun game, but the ending was a bit of a let-down.
